Hello,
I want to create desktop sharing application as system service.
At the moment I had created sharing and viewer applications like that http://www.c-sharpcorner.com/uploadfile/ulricht/how-to-create-a-simple-screen-sharing-application-in-C-Sharp/[^]
and created system service(but don't know how it use).

Problem is when I want to open computer manager (right click computer->manage).
I see only a pause with black screen on my viewer and need to accept User Account Control (UAC) on sharer computer.
I want to have full control by my viewer application on sharer computer.

I hope that someone have solution for this problem and help me. :)

Regards.
